Description

Technical Field

[0001] This invention relates to the field of low-voltage electrical equipment technology, and in particular to an intelligent low-voltage integrated control device and system. Background Technology

[0002] Indoor low-voltage electrical boxes are mostly enclosed or semi-enclosed structures with limited ventilation space, making it easy for heat to accumulate inside and causing the internal temperature to rise. If the temperature is not properly controlled, when the internal temperature exceeds the tolerance threshold of the low-voltage equipment, it will directly lead to a decrease in equipment operational stability, data transmission delays, and a shortened service life. In severe cases, it may even cause equipment short circuits, system crashes, and other malfunctions, affecting the normal operation of the entire low-voltage system.

[0003] Meanwhile, indoor environments inevitably contain pollutants such as moisture and dust. During the rainy season, in humid coastal areas, or in poorly ventilated spaces, moisture can easily penetrate the interior of the low-voltage electrical box and condense on the equipment surface, causing circuit board corrosion and interface oxidation, which can lead to problems such as poor equipment contact and short circuits. Dust, on the other hand, will adhere to the heat dissipation components, circuit boards, and interfaces of the low-voltage electrical equipment, hindering heat dissipation and exacerbating heat accumulation problems. It may also reduce the insulation performance of the internal circuits, increasing the risk of malfunctions.

[0004] In existing technologies, indoor low-voltage boxes mostly use passive cooling or active cooling with fixed-speed cooling fans for temperature control. Passive cooling is inefficient and cannot meet the cooling needs of multiple devices operating simultaneously. Fixed-speed fans lack dynamic adjustment capabilities, have low temperature control accuracy, and consume a lot of energy. They also make it difficult to balance cooling efficiency with the airtightness of the box. Regarding moisture and dust prevention, traditional low-voltage boxes rely solely on the box's own sealing structure for passive protection. Excessive sealing can further hinder heat dissipation, while insufficient sealing cannot effectively prevent moisture and dust from entering. Furthermore, they lack real-time monitoring and active purification mechanisms for humidity and dust concentration inside the box, making it impossible to respond promptly to dynamic changes in the indoor environment.

[0005] In addition, the existing power supply mode of low-voltage boxes mostly relies on a single mains power supply. When the mains power is interrupted, the low-voltage equipment in the box will stop operating directly, resulting in data loss or system paralysis. At the same time, there is a lack of comprehensive monitoring of equipment operating status and environmental parameters and remote operation and maintenance functions. Staff need to conduct regular on-site inspections to discover faults, which not only increases operation and maintenance costs, but may also cause greater losses due to the failure to detect faults in a timely manner.

[0006] In summary, existing indoor low-voltage boxes have significant shortcomings in terms of temperature control, moisture and dust prevention, power supply assurance, and operation and maintenance management, making it difficult to meet the requirements of low-voltage equipment for a stable operating environment. Therefore, there is an urgent need for an intelligent low-voltage integrated control solution with intelligent temperature control and heat dissipation, active moisture and dust prevention and purification, reliable power supply, and remote operation and maintenance functions to solve the defects of existing technologies. Summary of the Invention

[0042] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0043] Example 1

[0044] Reference Figure 1-3 and Figure 6An intelligent low-voltage integrated control device includes a low-voltage box 1, low-voltage equipment 2, an integrated control module 21, an intelligent temperature control and heat dissipation module, a moisture-proof and dust-proof purification module, a power supply module, and a status monitoring module. The integrated control module is electrically connected to the intelligent temperature control and heat dissipation module, the moisture-proof and dust-proof purification module, the power supply module, the status monitoring module, and the low-voltage equipment 2 in the low-voltage box 1 to realize data interaction and collaborative control.

[0045] The intelligent temperature control and heat dissipation module is used to collect temperature data inside the weak current box 1 and dynamically adjust the heat dissipation or heating mode according to the instructions of the integrated control module 21, while adjusting the opening status of the heat dissipation channel. The intelligent temperature control and heat dissipation module includes a temperature acquisition unit, an adaptive heat dissipation unit and a heat dissipation channel adjustment unit. The temperature acquisition unit uses a first temperature sensor 15, which is installed on the top inside the weak current box 1 to collect the real-time temperature of the key equipment area inside the weak current box 1.

[0046] The adaptive heat dissipation unit includes a brushless DC cooling fan 13. A fan slot 7 is provided on the side wall of the low-voltage box 1. The brushless DC cooling fan 13 is fixedly installed in the reserved position of the fan slot 7 on the inner side wall of the low-voltage box 1. The brushless DC cooling fan 13 is fixed to the preset installation position on the inner side wall of the low-voltage box 1 by a snap-on method. The air inlet of the brushless DC cooling fan 13 faces the area of ​​the low-voltage equipment 2 inside the low-voltage box 1, and the air outlet is aligned with the electrically adjustable louver 8. A rubber gasket is installed at the contact point between the brushless DC cooling fan 13 and the low-voltage box 1.

[0047] The heat dissipation channel adjustment unit includes an electrically adjustable louver 8, which is embedded in the side wall of the weak current box 1 and located directly opposite the air outlet of the brushless DC cooling fan 13.

[0048] The moisture-proof and dust-proof purification module is used to monitor the humidity and dust concentration inside the weak current box 1, and to start the moisture-proof and air purification operation according to the instructions of the integrated control module 21. The moisture-proof and dust-proof purification module includes an environmental sensing unit, a moisture-proof dehumidification unit and a dust removal and purification unit. The environmental sensing unit includes a humidity sensor 16 and a dust sensor 17, both of which are installed inside the weak current box 1.

[0049] The moisture-proof and dehumidification unit includes a small condenser dehumidifier 4, which is fixed to the side wall of the weak current box 1 by a buckle 3. The bottom air inlet is connected to the lower end of the weak current box 1 through an air inlet pipe 5, and the exhaust end is connected to the upper end of the weak current box 1 through an exhaust pipe 6.

[0050] The dust removal and purification unit includes a small negative pressure fan 9, an air purification box 10, an exhaust pipe 14, an air supply pipe 11, and a return pipe 12. The small negative pressure fan 9 and the air purification box 10 are both fixedly installed on the upper part of the weak current box 1. The air purification box 10 is filled with clean water. The exhaust pipe 14 is connected between the air inlet of the small negative pressure fan 9 and the interior of the weak current box 1. The air supply pipe 11 is connected between the air outlet of the small negative pressure fan 9 and the lower end of the liquid surface of the air purification box 10. The return pipe 12 is connected between the upper end of the liquid surface of the air purification box 10 and the top air inlet of the small condenser dehumidifier 4.

[0051] The power supply module adopts a dual-power supply mode to supply power to all modules of the device and the low-voltage equipment 2 in the low-voltage box 1. The power supply module includes an external mains power supply unit and an energy storage power supply unit. The external mains power is converted into 12V DC power by the AC / DC power supply module. The energy storage power supply unit is powered by an energy storage battery. The energy storage battery is a lithium iron phosphate battery with a capacity of 10Ah, which is installed in the battery mounting slot reserved on the inner side wall of the low-voltage box 1 and fixed with screws.

[0052] The status monitoring module is used to monitor the environmental parameters inside the low-voltage box 1 and the operating status of the low-voltage equipment 2, and send abnormal early warning signals to the integrated control module 21. The status monitoring module includes voltage and current sensors and a camera.

[0053] In this embodiment, the intelligent low-voltage integrated control device takes the integrated control module 21 as the core hub. Each functional module obtains a stable 12V DC power through the power supply module (prioritizing external mains power, which is converted by the AC / DC power supply module; when the mains power is interrupted, it automatically switches to a 10Ah lithium iron phosphate energy storage battery to ensure uninterrupted system operation) and establishes a two-way data interaction and control connection with the integrated control module 21 to realize full-process intelligent management and control of the environment inside the low-voltage box 1 and the low-voltage equipment 2.

[0054] In terms of temperature control, the first temperature sensor 15 installed on the top of the weak current box 1 collects the temperature data of the key equipment area in the box in real time and uploads it to the integrated control module 21. The integrated control module 21 dynamically adjusts the intelligent temperature control heat dissipation module according to the preset temperature threshold.

[0055] When the temperature inside the chamber exceeds the equipment's tolerance threshold, the integrated control module 21 instructs the brushless DC cooling fan 13 to start, and simultaneously controls the electrically adjustable louvers 8 to open to the corresponding angle, forming a rapid airflow channel inside the chamber to dissipate the heat generated by the equipment operation; when the temperature inside the chamber drops to a safe range, the integrated control module 21 gradually reduces the fan speed and narrows the louver opening angle to balance heat dissipation efficiency and chamber sealing.

[0056] For moisture-proofing, dust-proofing, and purification, humidity sensor 16 and dust sensor 17 installed inside the low-voltage box 1 monitor the humidity and dust concentration data inside the box in real time. When the humidity exceeds the standard, the integrated control module 21 starts the small condenser dehumidifier 4. The dehumidifier draws air from the lower end of the low-voltage box 1 through the air inlet pipe 5, and after internal condensation and dehumidification, the dry air is sent back to the upper end of the box through the exhaust pipe 6, forming a circulating dehumidification of the air inside the box.

[0057] When the dust concentration exceeds the standard, the integrated control module 21 synchronously starts the small negative pressure fan 9, which draws air from the clean water body above the liquid surface of the air purification box 10 through the air extraction pipe 14. Under the action of negative pressure, the dust-laden air in the weak current box 1 enters the clean water body of the air purification box 10 through the air supply pipe 11. The dust particles are adsorbed and filtered by the water body. The purified air is transported to the top air inlet of the small condenser dehumidifier 4 through the return pipe 12 and sent back to the weak current box 1 together with the dehumidified air.

[0058] In terms of status monitoring and remote operation and maintenance, the voltage and current sensors of the status monitoring module collect the power supply parameters of the weak current equipment 2 in real time, and the camera simultaneously captures the operation of the equipment in the box. Both types of data are uploaded to the integrated control module 21.

[0059] Furthermore, in this embodiment, when the brushless DC cooling fan 13 is installed, an infrared remote control oscillation module is embedded in the preset installation position, and an infrared sensor is added inside the weak current box 1 to work in conjunction with the first temperature sensor 15.

[0060] The first-channel temperature sensor 15 monitors the overall temperature inside the chamber, while the infrared sensor scans the temperature distribution in different areas of the chamber in real time, accurately locating the specific locations with higher temperatures. This multi-dimensional temperature data is then synchronously fed back to the integrated control module 21. When the integrated control module 21 determines that the temperature inside the chamber exceeds the standard and there are localized high-temperature areas, it activates the semiconductor cooling chip 19 to cool the water inside the air purification chamber 10, introducing cool air into the chamber. Simultaneously, it sends a command to the infrared remote control oscillation module to drive the brushless DC cooling fan 13 to direct its exhaust towards the higher-temperature areas, achieving directional and precise airflow. At the same time, the integrated control module 21 dynamically adjusts the fan speed and the opening angle of the electrically adjustable louvers 8 based on the temperature difference in the localized high-temperature areas, accelerating the flow of hot air in these areas. This, combined with the cooled purified air, quickly removes localized heat, preventing heat accumulation. Compared to traditional all-area cooling modes, this temperature control is more targeted and efficient.

[0061] Example 2

[0062] Reference Figure 4An intelligent low-voltage integrated control device, which differs from Embodiment 1 in that a semiconductor cooling chip 19 is embedded in the bottom of the air purification box 10, and multiple heat dissipation fins 20 are provided through the side wall of the air purification box 10. A second temperature sensor 18 is fixedly installed at the end of the heat dissipation fins 20 on the upper end of the low-voltage box 1.

[0063] In this embodiment, all other aspects are the same as in Embodiment 1, except that there are optimizations in terms of moisture-proof, dust-proof and purification aspects.

[0064] Humidity sensor 16 and dust sensor 17 collect humidity and dust concentration data in the low-voltage box 1 in real time and upload them to the integrated control module 21.

[0065] When the dust concentration exceeds the standard, the integrated control module 21 starts the small negative pressure fan 9. Under the action of negative pressure, the dust-laden air in the weak current box 1 enters the clean water at the bottom of the air purification box 10 through the exhaust pipe 14, and the dust particles are fully adsorbed and filtered by the water.

[0066] At the same time, the integrated control module 21 activates the semiconductor cooling chip 19 embedded in the bottom of the air purification box 10 to cool the clean water in the air purification box 10. The second temperature sensor 18 installed at the end of the heat dissipation fins 20 monitors the water temperature data in real time and feeds it back to the integrated control module 21 to ensure that the water is maintained in a suitable cooling range. The heat dissipation fins 20 quickly dissipate the heat generated by the semiconductor cooling chip 19 to ensure cooling efficiency.

[0067] After being filtered and cooled by clean water, the cold air is transported from the upper part of the liquid surface of the air purification box 10 through the return pipe 12 to the top air inlet of the small condenser dehumidifier 4. If the humidity sensor 16 detects that the humidity inside the box exceeds the standard, the cold air will first be dehumidified by the small condenser dehumidifier 4, and then sent back to the upper part of the weak current box 1 through the exhaust pipe 6. If the humidity meets the standard, it will directly flow back into the box through the exhaust pipe 6, forming an integrated air circulation. The purified cold air can directly reduce the ambient temperature inside the box, assisting the intelligent temperature control and heat dissipation module to achieve precise temperature control.

[0068] Regarding the main temperature control, the first-channel temperature sensor 15, installed at the top of the low-voltage box 1, collects the temperature of the key equipment area inside the box in real time. When the temperature inside the box is high and the purified air alone cannot meet the temperature control requirements, the integrated control module 21 starts the brushless DC cooling fan 13 and adjusts the opening angle of the electrically adjustable louvers 8 to accelerate the exhaust of hot air and the circulation of cooled and purified air inside the box, quickly reducing the temperature inside the box. When the temperature drops to a safe range, the integrated control module 21 reduces the fan speed and reduces the opening of the louvers to balance heat dissipation efficiency and sealing.

[0069] Example 3

[0070] Reference Figure 5 An intelligent integrated control device for low-voltage electrical systems differs from embodiments 1 and 2 in that a water collection cylinder 22 is fixedly installed at the lower end of the side wall of the low-voltage box 1. The upper end of the water collection cylinder 22 is connected to the condensate drip outlet of the small condensing dehumidifier 4 through a condensate guide pipe 24. A micro liquid pump 23 is fixedly installed at the top of the water collection cylinder 22. The liquid inlet of the micro liquid pump 23 is connected to the lower end of the water collection cylinder 22, and the liquid outlet is connected to the upper end of the air purification box 10 through a water supply pipe 25. A drain pipe 26 is provided on the back of the lower end of the air purification box 10. A solenoid valve 27 is installed on the drain pipe 26. The solenoid valve 27 and the micro liquid pump 23 are controlled sequentially and timed by an integrated control module 21.

[0071] In this embodiment, the device has advantages in terms of overall water circulation replenishment and discharge. The condensate generated by the small condenser dehumidifier 4 flows into the water collection cylinder 22 fixed at the lower end of the side wall of the weak current box 1 through the condensate guide pipe 24.

[0072] After the device has been running for a period of time, the integrated control module 21 first opens the solenoid valve 27 at regular intervals to discharge the wastewater that has absorbed a large amount of dust in the air purification box 10. After the drainage is completed, the solenoid valve 27 closes. Then, the micro liquid pump 23 is started to transport the condensate stored in the water collection tank 22 to the air purification box 10 through the water replenishment pipe 25 to replenish the clean water. This cycle repeats, forming an automated closed loop of condensate collection, wastewater discharge, and condensate replenishment, which can maintain the cleanliness of the water in the air purification box 10 without manual intervention.

[0073] Reference Figure 7 An intelligent low-voltage integrated control system includes the aforementioned intelligent low-voltage integrated control device, remote monitoring platform, and mobile terminal.

[0074] The integrated control module 21 of the intelligent low-voltage integrated control device establishes a two-way communication connection with the remote monitoring platform through the wireless communication module. The integrated control module 21 uploads the collected data such as temperature, humidity, dust concentration, operating status of low-voltage equipment 2 and power supply status in the low-voltage box 1 to the remote monitoring platform in real time. The remote monitoring platform has data storage, display and command issuance functions, and issues commands to the integrated control module for temperature control strategy adjustment, heat dissipation channel control, moisture-proof dust removal start-up and fault emergency handling.

[0075] The remote monitoring platform and the mobile terminal establish a communication connection through the mobile network. When the intelligent low-voltage integrated control device detects that environmental parameters exceed the standard, equipment operation is abnormal, or power supply is faulty, the remote monitoring platform receives the warning signal and automatically pushes the warning information to the mobile terminal.

[0076] The wireless communication module uses 4G, 5G or Wi-Fi modules; the remote monitoring platform adopts a B / S architecture and supports multi-terminal access; the mobile terminal is adapted to the Android or iOS operating system, and the early warning information is presented in the form of SMS and APP push.

[0077] The overall workflow of the system is as follows: The intelligent low-voltage integrated control device uses a first-channel temperature sensor 15, humidity sensor 16, dust sensor 17, voltage and current sensor, a second-channel temperature sensor 18, and a camera to collect real-time data on temperature, humidity, dust concentration, operating status of low-voltage equipment, and power supply status within the low-voltage box 1, which is then aggregated to the integrated control module 21. The integrated control module 21 uploads the collected data to a B / S architecture remote monitoring platform in real-time via a 4G / 5G / Wi-Fi wireless communication module. The remote monitoring platform stores and displays the data, allowing staff to view the real-time status and issue commands as needed, such as temperature control adjustment, heat dissipation channel control, moisture-proof and dust removal activation, and emergency fault handling. When environmental parameters exceed limits, equipment malfunctions, or power supply failures are detected, the integrated control module sends an early warning signal to the remote monitoring platform, which then pushes the warning to Android / iOS mobile terminals via SMS and APP push notifications. After receiving the remote commands, the control device uses the integrated control module 21 to drive the corresponding functional modules to perform operations, ensuring the stability of the environment and equipment operation within the low-voltage box 1.
